Definitions
- ethylene/unsaturated ester copolymer is the copolymer of ethylene and one or more unsaturated ester monomers.
- Useful unsaturated esters include: 1) vinyl esters of aliphatic carboxylic acids, where the esters have from 4 to 12 carbon atoms, and 2) alkyl esters of acrylic or methacrylic acid (collectively, "alkyl (meth)acrylate”), where the esters have from 4 to 12 carbon atoms.
- Another useful ethylene copolymer includes ethylene/(meth)acrylic acid copolymer, which is the copolymer of ethylene and acrylic acid, methacrylic acid, or both.
- polyamides of the type that may be formed by the polycondensation of one or more diamines with one or more diacids include aliphatic polyamides such as poly(hexamethylene adipamide) ("nylon-6,6"), poly(hexamethylene sebacamide) (“nylon-6,10”), poly(heptamethylene pimelamide) ("nylon-7,7"), poly(octamethylene suberamide) ("nylon-8,8”), poly(hexamethylene azelamide) (“nylon-6,9”), poly(nonamethylene azelamide) (“nylon-9,9”), poly(decamethylene azelamide) (“nylon-10,9”), poly(tetramethylenediamine-co-oxalic acid) (“nylon-4,2”), the polyamide of n-dodecanedioic acid and hexamethylenediamine (“nylon-6,12”), the polyamide of dodecamethylenediamine and n-dodecanedi
- Representative aliphatic/aromatic polyamides include poly(tetramethylenediamine-co-isophthalic acid) ("nylon-4,I”), polyhexamethylene isophthalamide (“nylon-6,I”), polyhexamethylene terephthalamide (“nylon-6,T”), poly (2,2,2-trimethyl hexamethylene terephthalamide), poly(m-xylylene adipamide) (“nylon-MXD,6”), poly(p-xylylene adipamide), poly(hexamethylene terephthalamide), poly(dodecamethylene terephthalamide), and polyamide-MXD,I.
- any of the layers of the film may have a thickness of at least about, and/or at most about, any of the following: 0.05, 0.1, 0.5, 1, 1.3, 1.5, 2, 2.5, 3, 4, 5, and 6 mils. Any of the layers of the film may have a thickness as a percentage of the total thickness of the film of at least about, and/or at most about, any of the following: 1, 3, 5, 7, 10, 15, 20, 25, 30, 35, 40, 45, and 50 percent.
- the minimum bond strength between the intermediate layer and each of the layers directly adjacent the intermediate layer may be at least about any of the following: 1, 1.5, 2, 2.5, 2.6, 2.8, 3, 3.5, 4, and 4.5 pounds/inch measured according to ASTM F904.
- the film may be oriented in either the machine (i.e., longitudinal), the transverse direction, or in both directions (i.e., biaxially oriented), for example, to enhance the strength, optics, and durability of the film.
- a web or tube of the film may be uniaxially or biaxially oriented by imposing a draw force at a temperature where the film is softened (e.g., above the vicat softening point; see ASTM 1525) but at a temperature below the film's melting point.
- the film may then be quickly cooled to retain the physical properties generated during orientation and to provide a heat-shrink characteristic to the film.
- the film may be oriented using, for example, a tenter-frame process or a bubble process.
- One or more of the layers of the film -- or at least a portion of the entire film may be cross-linked, for example, to improve the strength of the film.
- Cross-linking may be achieved by using chemical additives or by subjecting one or more film layers to one or more energetic radiation treatments -- such as ultraviolet, or ionizing radiation such as X-ray, gamma ray, beta ray, and high energy electron beam treatment -- to induce cross-linking between molecules of the irradiated material.
- one or more film layers may be extruded and irradiated, and any of the PVdC-containing layer, the intermediate layer, and subsequent layers may then be applied to the irradiated substrate, for example, by an extrusion coating process. This will produce an extrusion coating interface, as referenced in the Additional Film Layers section above. Further, the PEC of the intermediate layer may be substantially devoid of crosslinks.
- the product may be inserted into the bag, and the open end of the bag sealed to enclose the product.
- the film may also be wrapped around a product and heat sealed to form a package enclosing the product.
- the film may be used as a wrap to cover and secure a product (e.g., a food product) that rests on a tray.
- the film may be used as a lid adapted to be sealed to a support (e.g., a tray) for the packaged product.

- any numerical value ranges recited herein include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value.
- the amount of a component or a value of a process variable e.g., temperature, pressure, time
- the amount of a component or a value of a process variable may range from any of 1 to 90, 20 to 80, or 30 to 70, or be any of at least 1, 20, or 30 and/or at most 90, 80, or 70, then it is intended that values such as 15 to 85, 22 to 68, 43 to 51, and 30 to 32, as well as at least 15, at least 22, and at most 32, are expressly enumerated in this specification.
